Weather stripping



Patent ed Jan. 7, 1930 UNITEDFSTATES PATENT OFFICE MAURICE E. BOSLEY, OFCHICAGO, ILLINOIS, ASSIGNOR TO THE I). W. BOSLEY COM- PANY, OF CHICAGO,ILLINOIS, A CORPORATION OF ILLINOIS WEATHER STRIPPING Application filedAugust 20, 1927. Serial No. 214,370.

. This invention relates in general to Weatherstripping and hasparticular reference to an improved weather-tight gasket adapted for usein connection with movable closures for sealing the crevices between theclosure members when in closed position.

My invention contemplates the provision. of, an improved Weatherstrip ofthe type comprising a soft flexible core encased in a sleeve, the edgesof which are extended at a side and foldedand seamed together to providean attaching flange. Such weatherstrips when arranged between closuremembers that compress the packing require little strength in the flange,but where the closure is against the Weatherstrip without acompanionmember back of it, as when the pressure comes in the plane ofthe attaching flange, tendency is provided for the strip to give backbetween the points of fastening of the flange and in this event toresult in an uneven pressure at these points and the spacestherebetween.

The principal object of the invention is the provision of a Weatherstriphaving a strengthening member disposed longitudinally therein for thepurpose of maintaining a tight engagement, throughout the length of theWeatherstrip, between the weatherstrip body and a closure member enga'ng the body in a direction parallel with the p ane of the attachingflange.

A further important object of the invention is the provision of aWeatherstrip having a strengthening longitudinal insert disposed in theflange thereof adjacent the body portion for the purpose ofstrengthening and supporting the body in operative position.

Another important object of the invention is the provision of aWeatherstrip adapted to conform with, and to maintain close engagementupon, uneven or discontinuous surfaces. When weatherstripping is securedupon a closure member having warped or otherwise discontinuous surfaces,or when the Weatherstrip is positioned upon a corner of a closuremember, there is a tendency for the Weatherstrip portions to draw awayfrom close engagement upon the closure member and difliculty isfrequently experienced in arranging the Weatherstrip to maintain itsengaged position upon the member at points immediately adjacent the apexof the corner,

the resilience of the Weatherstrip causing a continuous curvature ratherthan a sharp bend conforming with the. angle of the clo sure corner.

Another important object of the invention is the provision of aWeatherstrip having an attaching flange in which there is en: closed aflexible stiffening member adapted to be bent into conformity with thecontour of the closure member upon which the Weatherstrip is secured andto maintain a close engagement of the Weatherstrip upon uneven surfaces.

Another important object of the invention is the provision of aWeatherstrip especially adapted for close engagement upon the angularportions of a closure member.

Another important object of the invention is the provision of aWeatherstrip having a bendable insert enclosed within the attachingflange in order to maintain the flange properly in arranged positionupon a closure member without using a large number of nails or similarfastening devices.

Numerous other objects of the invention will be apparent as it is betterunderstood from the following description, which, taken in connectionwith the accompanying drawirgs, discloses a preferred embodiment there-0 Referring to the drawings:

Figure 1 is a perspective view of a weatherstrip embodying my invention,portions of which are shown in cross-section;

Fig. 2 is a plan view illustrating the Weatherstrip assembled upon aclosure memher, the parts being arranged to show the Weatherstripcompressed by forces acting parallel with the plane of the attachingflange, and

Fig. 3 is a cross-section taken substantially on the line 33 of Fig. 2.

To illustrate my invention I have shown on the drawing a Weatherstripcomprising a core or rope 11 formed of suitable resilient packingmaterial and an enclosing sleeve 12, the mid-portion 13 of which iswrapped about and encloses the resilient core 11 to form a substantiallycylindrical Weatherstrip body, and the edges 14 and 15 of which compriseflanges which extend laterally from the cylindrical body portion of theWeatherstrip. These flanges 14 and 15 engage at their junction with thebody portion and extend adjacently outward. The extreme edge portion 17of the upper flange 15 extends outwardly beyond and overlaps the outeredge .of the lower flange 14, and is folded back along a line of bend 16and engages the lower surface of the flange 14 to provide an integral,outwardly extending, three-ply attaching flange 18, the fly edge 19 ofthe portion 17 having final engagement upon the body of the Weatherstripadjacent the base of the flange 18. An insert 21 comprising a strand,roll, or rod of suitable flexible material, is enclosed within the bodyof the flange 18 and adjacent the body portion of the Weatherstrip,being inserted and positioned between the flange portions 14 and 15. Theinter-folded portions 14, 15 and 17 are secured together on each side ofthe insert by means of a seam 22 formed at the base of the flangebetween the insert and the body portion, and a seam 23 formed in thebody of the flange. These seams secure the insert in position in theflange, the seam 21 also performing the function of securing themid-portion 18 of the sleeve about the resilient core 11 of theWeatherstrip. The interfolded flange portions may also be securedtogether bymeans of a seam 24 formed in the flange adjacent its outeredge.

The Weatherstrip is especially adapted for assembly upon a door frame25, as shown in Figs. 2 and 3 of the drawing, in a position in which adoor member 27 closes against the body of the Weatherstrip in adirection parallel with the plane of the flange 18. The Weatherstrip issecured in position by means of nails or similar fastening devices 27,which pass through the flange at spaced intervals and take into theclosure member 25. It will be apparent that the portions of theweatherstrip body opposite the fastening members 27 will be supportedfirmly by the flange and will have a firm engagement with the closure Imember 26, whereas in the absence of the strengthening member 21, theWeatherstrip bodyintermediate the members 27 will not firmly engage theclosure member because the flange parts. which back the resilient bodyportion, will sag somewhat between the fastening devices. By providingthe longitudinal strengthening member 21, the intermediate portions ofthe flange are held firmly in position against sagging and theweatherstrip body is backed up so that a uniform engagement betweenstrip and closure member is provided.

The insert not only serves the purpose of stiffening the Weatherstripbody intermediate the fastening members, but also provides means formaintaining the Weatherstrip flange in any position in which it may bear ranged. This construction provides a weatherstrip which may bearranged in close engagement upon uneven surfaces and one, which, havingbeen disposed in a definite position, will maintain such positionagainst the tension of the natural resilience of the weatherstrip which,after distortion, tends to reassume a normally straight position and todraw away from depressions or other irregularities of the surface uponwhich the Weatherstrip is positioned. Since the strengthening member isadapted to maintain the flange properly in a definite engaged position,fewer fastening devices are needed to secure the Weatherstrip in place.Not only is economy of fastening devices thus effected, but since thefastening flange is weakened wherever a fastening device passes through,a Weatherstrip which requires fewer fastening devices to maintain it inposition is inherently a more durable and satisfactory article.

It is thought that the invention and many of its attendant advantageswill be understood from the foregoing description, and it will beapparent that many changes may be made in the form, construction andarrangement of the parts without departing from the spirit and scope ofthe invention or sacrificing all of its material advantages, the formhereinbefore described being merely a preferred embodiment thereof.
